COUPLING AND ASSOCIATED METHOD OF TRANSFERRING TORQUE

The coupling (30) can have a female member (32) configured to rotate around an axis, defining an axial recess (36), and having a plurality of connections (52) circumferentially arranged along a radially inner face (38); a male member (34) extending inside the axial recess (36) concentrically to the female member (32) and having a plurality of connections (50) circumferentially arranged along a radially outer face (40); and a plurality of circumferentially arranged links (44), each link (44) having an inner end (46) engaged with a corresponding one of the male member connections (50), and an outer end (48) engaged with a corresponding female member connection (52), the links (44) being slanted off the radial orientation, with the inner end (46) being circumferentially offset from the outer end (48), the links (44) subjected to compression when transmitting torque between the female member (32) and male member (34).
