Yes, a Torsen differential uses gears inside to transfer torque. It's a proven 20+ year old design. There aren't clutches inside causing the two wheels to lock up. Nor is there a viscous coupling to adjust transfer between wheels based on a speed difference.
these are still dumb mechanical differentials. The are subject to whatever compromises were made in the mechical design of the gears. A computer controlled torque vectoring differential like you find on higher end drivetrains (Evo X for example, or BMW M cars) are not subject to a fixed bias ratio curve.
