Couplings:

Couplings are mechanical devices used to connect two shafts together at their ends for transmitting power. In the context of motors, couplings are often used to connect the output shaft of a motor to another mechanical component, such as a gearbox, wheels, or other driven mechanisms. Couplings come in various designs, including flexible couplings, rigid couplings, jaw couplings, and more. The choice of coupling depends on factors such as torque, misalignment tolerance, and the specific application.
