1. A torque limiter, comprising:
a first body;
a second body, the first body and the second body extending around a central axis, the first body supporting first limiter teeth, the second body supporting second limiter teeth mating with the first limiter teeth, the first limiter teeth and the second limiter teeth defining (i) an engaged configuration wherein the first limiter teeth and the second limiter teeth are suitable for transmitting a torque about the central axis of the first body to the second body, and (ii) a release configuration, wherein the first limiter teeth and the second limiter teeth are inapt to transmit a torque between the first body and the second body;
locking means suitable for opposing a transition of the first limiter teeth and of the second limiter teeth from the release configuration thereof to the engaged configuration; and
limited-retaining means suitable for retaining the first limiter teeth and the second limiter teeth in the engaged configuration thereof when the torque is less than a transmission torque limit, and suitable for yielding when the torque exceeds the transmission torque, the limited-retaining means comprising:
at least one inner limited-retaining element comprising an outer contact surface; and
at least one outer limited-retaining element comprising an inner contact surface mating with said outer contact surface, the inner and outer limited-retaining elements having (i) a retaining configuration, wherein the inner limited-retaining element is clamped into the outer limited-retaining element, and (ii) a yielded configuration wherein the inner limited-retaining element is loosened from the outer limited-retaining element.
