A rigid torque-transmitting coupling includes two members and a coating on one member or on carrier disposed between the members. The carrier has opposing contact faces disposed against a separate member connection face. The coating includes a fixing layer disposed on the connection member face or one carrier face, and a plurality of particles are disposed within the fixing layer to secure the particles on the member or carrier. Each particle has a hardness of at least 9 on the Mohs scale and at least twenty-five percent of the particles within any area of the coating extend outwardly from the fixing layer outer surface. Further, each member contacts either the other member or the coating carrier with a pressure of about 90 MPa and 180 MPa. The surface(s) carrying the coating are formed of a harder material than the member faces engaged by the coating.
