ABSTRACT:
A coupling for transmitting a torque from a shaft to a hub provided with an internal chamber which can be pressurized and which is relieved when a relative rotational movement takes place in relation to the shaft due to an overload and which is secured against slipping off from the shaft seat in an axial direction by a two-part flange mounted on the shaft. The flange engages with a radial groove in the hub in a claw-like manner and carries a shear-off device for breaking off the plug sealing the internal pressure chamber.
