Abstract
According to the invention, a safety coupling, the torque transmission of which takes place as a result of the radial tension of a clamping sleeve which is under high pressure, has a release valve. During a rotation of the shaft relative to the hub, caused by overloading, the release valve is opened, so that the torque transmission is interrupted as a result of a reduction of the pressure in the clamping sleeve. After rotation, the tappet of the release valve is drawn into the release valve, so that the safety coupling can be put into operation again as a result of a pressure buildup, without any destruction or wear occurring.
