What is a defining feature of a universal joint compared to other coupling types?

A universal joint is specifically designed to accommodate angular misalignment between two shafts. This characteristic is crucial in applications where components cannot be perfectly aligned due to design constraints, vibrations, or shifts in position during operation. The universal joint allows for some degree of angle between the shafts while still transmitting torque effectively, making it ideal in vehicles, machinery, and other applications where flexibility in alignment is necessary.

In contrast, other coupling types may require precise alignment to function correctly, as they can be less tolerant of misalignment. This feature makes universal joints unique and particularly valuable in various engineering and mechanical contexts. The ability to handle angular misalignment while maintaining functionality distinguishes it from couplings designed for direct, linear connections.
