Abstract
One or more variable stiffness devices may be positioned between the splined coupling of a pair of rotating mechanical components to reduce or substantially eliminate backlash during operation. The variable stiffness device may include a spring pin that exerts a variable biasing force on mating surfaces of the pair of rotating mechanical components to maintain a relative position of the components in response to rotational and/or torsional forces exerted during operation.
