ABSTRACT:
In order to prevent expensive subsequent damage because of a shaft fracture in machines which are coupled together, one of the two shaft ends is provided outside of one coupling flange with a predetermined breaking point. At one coupling flange a safety element is mounted which extends past the axial length of the predetermined breaking point. The safety element can be constructed as a pin rotatably mounted inside the shaft end or as a safety ring mounted around the shaft end to hold a fractured shaft in the predetermined position until standstill without it being possible for the shaft to be deflected.
