Abstract

Apparatus for detecting a parameter associated with the torque transmitted by a friction clutch, where the friction clutch has a clutch disk which is or can be connected for rotation in common to a power takeoff shaft. The apparatus includes a receiver area, which does not rotate with the clutch disk in the torque-transmitting state, and a code provided on the clutch disk. The code can be scanned by the receiver area and thus generates a sensor signal associated with transmitted torque.
