Yes it does, otherwise the back wheels will try to turn at a different speed to the front ones and the Torsen will explode
 D2 and C5 diffs are the same so loads of options. The heatsink from the RS6 diff will even fit if we're getting ambitious

Yeah basically. The gearbox output shaft drives the outer case of the Torsen. The inner gears of the Torsen then drive two outputs - one front, and one rear. The front output goes through a set of gears to shift it sideways and reverse its direction, and then it goes forward to drive the front diff inside the gearbox casing. The rear output goes straight out of the back and hooks up to the propshaft and rear diff. Because both front and rear diffs are being driven at the same speed they both have exactly the same ratios, abeit packaged slightly differently
 This diagram shows the concept well. Its of a DSG unit, but the principle is the same for all Audi AWD (longitudinal) gearboxes (manual or auto). The Torsen is shown in red on the bottom right.  For completeness, the A3 and TT transverse setups are completely different. Oh, here is a rather odd mirror-image of the 5HP24A which shows it too:
