Abstract
An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mourned to the housing, a first biasing element rotationally urging the spindle toward a spindle home position, and a second biasing element rotationally urging the spring collar toward a spring collar home position. The apparatus may further include a handle mounted on the chassis such that the chassis biases the handle to a handle home position with a return torque. The handle is engaged with the spindle such that the first biasing element contributes to the return torque. In certain embodiments, the handle may further be engaged with the spring collar such that the second biasing element contributes to the return torque.
