1. A torque limiter (TL) for torque transmission (TT) to downstream components, comprising:
an input shaft comprising reaction faces;
an output shaft defining slots; and
a torsional spring comprising first and second tangs initially offset from one another, the torsional spring being preloadable by a preload torque to align the first and second tangs whereupon the torsional spring is fittable about the output shaft with the output shaft fit about the input shaft and with the first and second tangs respectively engaging with the slots and the reaction faces, and,
for input shaft rotation:
first TT paths proceed from the input shaft to the output shaft through the torsional spring when downstream torque of the downstream components deceeds the preload torque, and
a second TT path proceeds from the input shaft to an external structure when the downstream torque exceeds the preload torque.
