The inventors have appreciated that when conventional keyless couplings are used to couple a keyless shaft to a machine member (gear, pulley, etc.), a shaft-hole connection is used to transmit torque. The fit precision of the coupler and the matched shaft end determines the transmission quality, and the coupler and the keyless shaft are in interference fit for improving the installation quality due to the fact that friction force is needed to transmit torque; and the interference fit requires that the machining precision of the inner diameter of the coupler and the outer diameter of the keyless shaft is higher.
