The Torah (Law/Instruction in Hebrew) is the Ten Commandment..
And not the "Torah" as we know today.. by definition...
Now the name 'Torah' refer to compilation of "Five Books (which they say) Written By Moses".
Oddly enough although those books are said to be written by Moses, there are story within regarding Moses death.. hmmm Moses is quite 'magnificent' to be able to write a story regarding his own death. (sarcastic mode on)
The 'original Torah' a.k.a Ten Commandments supposedly being written in the stone tablet which went missing.
And theoretically it should be written in 'iconic script' such as the egyptian hieroglyph, given the 'israelites' has not yet adopted "Consonant based Phoenician script" during that time..
When the Quran refer to "Torah" (instruction) it meant the "Ten Commandments".
When the Quran refer to Zaboor, "The Book of David" it meant the "Psalms".
Salam / Peace
Psalms are David's poetry so your talk of Moses not writing the Torah is not relevant as the Koran never said he did. As far as the ten commandments these are what God gave Moses in tablet form. It is not accurate to say that the Torah is the ten commandments because the Koran clearly said "let them bring forth the Torah" and also said that prostration to the ground is found in the Torah.
Muhammad is the Messenger of God. Those who are with him are hard against the unbelievers merciful one to another. You see them bowing, prostrating, seeking blessing, bounty and good pleasure (of God). Their mark is on their faces, the trace of prostration. That is their likeness in the Torah, and their likeness in the Gospel as a seed that puts forth its shoot, and strengthens it, and it grows strong and rises straight upon its stalk, pleasing the sowers, that through them it may enrage the unbelievers. God has promised those of them who believe and do deeds of righteousness forgiveness and a mighty wage(4829)

As fas as what Torah generally means it means the scriptures the Jews have and even the Jews someimes used the Torah to describe all the scriptures and not just the 5 books of Moses. These definitions are human definitions and change according to the times.
The earliest name for the first part of the Bible seems to have been "The Torah of Moses." This title, however, is found neither in the Torah itself, nor in the works of the pre-Exilic literary prophets. It appears in Joshua (831?32; 236) and Kings (I Kings 23; II Kings 146; 2325), but it cannot be said to refer there to the entire corpus. In contrast, there is every likelihood that its use in the post-Exilic works (Mal. 322; Dan. 911, 13; Ezra 32; 76; Neh. 81; II Chron. 2318; 3016) was intended to be comprehensive. Other early titles were "The Book of Moses" (Ezra 618; Neh. 131; II Chron. 3512; 254; cf. II Kings 146) and "The Book of the Torah" (Neh. 83) which seems to be a contraction of a fuller name, "The Book of the Torah of God" (Neh. 88, 18; 1029?30; cf. 93).

The word "Torah" is a tricky one, because it can mean different things in different contexts. In its most limited sense, "Torah" refers to the Five Books of Moses Genesis, Exodus, Leviticus, Numbers and Deuteronomy. But the word "torah" can also be used to refer to the entire Jewish bible (the body of scripture known to non-Jews as the Old Testament and to Jews as the Tanakh or Written Torah), or in its broadest sense, to the whole body of Jewish law and teachings.
