A slaving and blocking device for transmitting a torque from a driving part to a driven part and for stopping the driven part at a torque engaging the driven part has a slaving unit fixable on the driving part fixed against relative rotation and having slaving claws that are offset from one another in a circumferential direction, a roller star wheel located in the slaving unit and connectable to the driven part fixed against relative rotation, clamping bodies located in freewheeling fashion between the slaving claws and points of a star of the roller star wheel, a stationary clamping ring located concentrically to the slaving means and the roller star wheel and having an inner annular face forming a counterpart clamping face for the clamping bodies, and radially displaceable centrifugal force elements located in the roller star wheel such that above a predetermined rpm the force elements clamp the roller star wheel firmly to the slaving means.
