Abstract: A coupling apparatus for a speed regulator, or governor, of a typed used on motor vehicles for example, comprises a hollow connecting stud which is affixed to a governor positioning drive at a driven end telescoped to a hollow adjustment piece at a driving end. The hollow adjustment piece has a cap with an opening therein. A coupling rod passes through the opening having a driven end enlargement directed toward the governor positioning drive and a connecting apparatus at the other end connected to a speed adjusting apparatus. The coupling rod slides through the cap opening but the driven end enlargement is larger than that portion of the opening through which the coupling rod extends and can, therefore, not slide therein.
