Described herein is a tensioner device, and assemblies and methods of manufacture thereof. The tensioner device may be adapted to create a target tension in an associated belt based on the measured length of the belt and/or measure characteristics of a biasing element, such as a stiffness of the biasing element. A biasing element may exhibit a measured stiffness and be associated with a damping assembly and a base of the tensioner device. An engagement member may be associated with the damping assembly for movement therewith and angularly displaceable relative to the base and the biasing element to tension the belt. In one example, the biasing element may be connected to the damping assembly at a position determined by the measured stiffness to define a value of the angular displacement of the engagement member relative to the biasing element and create a target tension in the belt.
