[0002] Couplings are widely used in various general-purpose machinery to connect two shafts so that they rotate together to transmit torque and motion.

[0003] Currently, all existing couplings are non-universal couplings (such as mechanical couplings, diaphragm couplings, plum blossom elastic couplings, etc.), which have size matching requirements for shaft diameters. In real applications, many shaft-to-shaft connections do not require high precision, but only require that they be connected to each other and can transmit a certain torque. In addition, the power shaft and the passive shaft often have different sizes. If traditional couplings are used, many couplings of different sizes that are suitable for the power shaft and the passive shaft must be processed and manufactured, which makes processing and use very inconvenient.
