universal coupling

The dominant universal coupling to the Z boson does not change flavor, but sub-dominant non-universal contributions can.

The first is that the dual output bevel gears allow the axles to swing around the drive axle without the need for universal couplings.

J. J. Sakurai in 1960 predicted that there should be a massive vector boson which is coupled to isospin, and predicted that it would show universal couplings.

During the company's early years through to 1950, it pioneered the development of various couplings and related products, including ground joint and air hammer couplings, malleable iron universal couplings with safety locking feature, steel combination nipples, steel hose menders, plated hose fittings, and dredge sleeve clamps.

A universal joint, universal coupling, U-joint, Cardan joint, Hardy-Spicer joint, or Hooke's joint is a joint or coupling in a rigid rod that allows the rod to 'bend' in any direction, and is commonly used in shafts that transmit rotary motion.
