Involute Splines and Serrations are used to connect rotational elements such as a gearbox-shaft and a coupling.

The flanks of the teeth are usually involute curves as the flanks of normal gear wheels. These can be milled efficiently and also the inspection is easily done by the help of measuring pins.

Some straight sided spline profiles exist (not parallel flanks) these are calles serrations or serrated shafts.
