💡 What is a shaft coupling used for in motion control systems?

A shaft coupling is a handy connector that links two shafts to transmit torque. - Helps transfer torque between shafts in hobby projects (torque transmission). - Handles small misalignment and cushions shock in DIY rigs (misalignment tolerance). - A handy, reliable choice for stepper motors, 3D printers, and CNC builds (machine compatibility).
