Abstract: A torque limiting coupling comprises rotary input and output members which are interconnected for limited torque transmission therebetween by coupling elements secured respectively to such members which are caused at a predetermined or overload torque to oscillate pivotally thus limiting the torque transmitted. According to a preferred construction, the input and output members are coupled by gimballed joints which are yieldingly restrained from free swiveling for permitting transmission of torque. The yielding restraint permits only a limited torque to be transmitted such that, if such limited torque is exceeded, swiveling of the gimballed joints causes the input and output members to slip relative to each other.
