Abstract
A torque transferring and monitoring device includes a coupling having a hub portion, a first rim portion, a first set of spokes radially extending between the hub portion and the first rim portion, a second rim portion spaced apart from the first rim portion and a second set of spokes radially extending between the hub portion and the second rim portion. The second set of spokes are axially spaced apart from the first set of spokes. A plurality of pins are fixed to the first rim portion. Each pin has a portion positioned in an aperture formed in the second rim portion. The pin is clear of the second rim portion when the coupling is in an unloaded state. The pin engages the second rim portion to transfer load between the first and second rim portions when a torque exceeding a predetermined magnitude is transferred through the coupling.
