Abstract: A slip coupling includes two coupling elements and a clamping nut screwed onto one coupling element to press the other coupling element against the one coupling element so that a torque acting on one coupling element is transmitted slip-free to the other coupling element and limited to a sliding torque as the coupling elements slip against one another. Free play disks are disposed between the clamping nut and the other coupling element. Interacting driver elements received by the clamping nut, the free play disks and the other coupling element enable the coupling elements to slip against one another up to a critical angle without rotation of the clamping nut. When clamping nut is caused to rotate, a contact pressure of the other coupling element on the one coupling element and thereby a holding torque transmittable in a slip-free manner is changed.
