A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft.
A rotary union is a union that allows for rotation of the united parts. It is thus a device that provides a seal between a stationary supply passage (such as pipe or tubing) and a rotating part (such as a drum, cylinder, or spindle ) to permit the flow of a fluid into and/or out of the rotating part.

The first mass-produced viscous couplings for a permanent 4WD off-road-capable vehicle were in the AMC Eagle, which was produced from 1980 to 1988 model years. [2] The AMC Eagle's single-speed model 119 New Process central differential used a viscous coupling filled with a liquid silicone-based material. [3]
A Schmidt coupling is a type of coupling designed to accommodate large radial displacement between two shafts. Consisting of an arrangement of links and discs—three discs rotating in unison, interconnected in series by three or more links between each pair of discs—a Schmidt coupling can adapt to very wide variations in radial displacement while running under load.
An improvised flexible coupling made of car tyre pieces connects the drive shafts of an engine and a water pump. This one is used to cancel out misalignment and dampen vibrations. Rotating coupling. A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is ...
A Rzeppa-type CV joint. A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
The Wedglock coupler is named for the pneumatic wedges that lock the moving parts of the coupler head in the engaged position. It is the standard automatic coupler used on London Underground trains. The coupler was introduced in 1936 [56] and is manufactured by William Cook Rail [57] and Voith. [58]
