Abstract: A rotary controller locking cap including a cap body having a longitudinal axis, a bore extending partially through the cap body along the longitudinal axis such that the cap body has an opening on a first side and is closed on an opposite second side, and an internally threaded portion arranged in the bore at least at the opening. The internally threaded portion is structured and arranged for threaded engagement with a threaded collar of a rotary controller. The bore is structured and arranged to accommodate an output shaft of the rotary controller therein while not contacting the output shaft when the cap body is engaged with the threaded collar. The cap body when engaged with the threaded collar is operable to preclude adjustability of the output shaft of the rotary controller.
