The automatic random reset torque limiter of the invention, connected between the crushing head of a gyratory crusher and its one-way anti-spin clutch, comprises a carrier element and a coaxial detent element that have end surfaces opposing one another across a small gap. The carrier has wells opening to its end surface that are equidistant from its axis and are uniformly spaced from one another. The detent element has hemispherical cavities in its end surface, one for each well, each alignable with a well. In each well is a coiled compression spring and a ball. The spring normally holds the ball engaged in a cavity but allows it to ride out of the cavity and roll on the detent element end surface while excessive torque persists.
