1. A torque feedback system for a vehicle comprising:

  • a steering shaft having a longitudinal axis;

    a jacket surrounding the shaft, the jacket including a contact portion, the shaft rotatable with respect to the jacket; and

    ,at least one mechanical energy storing element arranged to provide torque feedback when the steering shaft is rotated, the at least one mechanical energy storing element including a first mechanical energy storing element having a first end engageable with the jacket and a second end engageable with the shaft, and a second mechanical energy storing element having a first end engageable with the jacket and a second end engageable with the shaft, the first mechanical energy storing element torsion spring provides resistance to rotation of the shaft in a first rotational direction, and the second mechanical energy storing element provides resistance to rotation of the shaft in a second rotational direction;

    wherein rotation of the shaft in the first rotational direction separates the first end of the second mechanical energy storing element from the contact portion while maintaining contact of the first end of the first mechanical energy storing element with the contact portion, and rotation of the shaft in the second rotational direction separates the first end of the first mechanical energy storing element from the contact portion while maintaining contact of the first end of the second mechanical energy storing element with the contact portion.
