A motor vehicle friction clutch, including a reaction plate, a friction disc with friction liners at its outer periphery, a pressure plate, a cover plate, axial clutch engaging mechanism controlled by declutching and acting between the cover plate and the pressure plate through respective primary and secondary abutments, the pressure plate being fixed to the cover plate that is axially displaceable for rotation with the latter, also includes a wear compensating device. One of the abutments when the clutch is engaged is displaceable axially and the compensating device is brought into operation to effect the displacement. The actuating device is controlled by a displacement in association with a detection responsive to wear in the liners and acting on at least one of the elements consisting of the actuating, compensating and displacement means. Adjustment of the nominal position of the clutch when engaged defined by the axial distance between the primary and secondary abutments when the clutch is engaged.
