The central drive element is connected to a drive spindle by way of a ball ramp coupling and the ball ramp coupling has a drive output disc, which engages in the drive element, and a coupling ring, with the ends of a torsion spring being connected to either the disc or the ring. The torsion spring is a helical spring, preferably composed of a wound spring plate.
