A potentiometer device has a tubular body, an actuation shaft, splines, spline-receiving cavities, a potentiometer, a tubular housing, first and second annular cavities and retention balls. The splines are externally positioned about the actuation shaft. The spline-receiving cavities are internally positioned around the tubular body. The potentiometer has a housing body and a wiper pin. The tubular body is connected to the housing body. The tubular housing and the wiper pin are positioned within the housing body. The tubular housing is connected to the housing body. The wiper pin is mechanically coupled to the actuation shaft. The actuation shaft is removably positioned within the tubular body and the housing body. The first annular cavity internally and radially traverses into the tubular housing. The second annular cavity externally and radially traverses into an output coupling end of the actuation shaft. The retention balls are engaged within the first annular cavity.
