ABSTRACT:
A coupling apparatus where two coaxially held coupling halves are connected by a tensioning member provided with a predetermined breaking point. The tensioning member secured at one end to its associated coupling half, is radially and tangentially displaced with respect to the end of the tensioning member secured to the other coupling half. At the overload condition, one coupling half makes a complete rotation, after breaking, with respect to the other coupling half. A rotary escapement is provided as a holding structure so that when one element of the tensioning member swings, it does so out of the path of the other.
