1. A torsion spring comprising:

  • a middle plate having a first attachment point displaced from a geometric center of the middle plate;

    one or more first elastomeric elements, wherein one of the first elastomeric elements proximate to a first side of the middle plate is secured to the first side of the middle plate and, and wherein the one or more first elastomeric elements has an opening coincident with the first attachment point of the middle plate;

    one or more second elastomeric elements, wherein one of the second elastomeric elements proximate to a second side of the middle plate is secured to the second side of the middle plate, and wherein the one or more second elastomeric elements has an opening coincident with the first attachment point of the middle plate;

    a first outer plate secured to one of the first elastomeric elements proximate to the first outer plate and having an opening coincident with the first attachment point of the middle plate; and

    a second outer plate secured to one of the second elastomeric elements proximate to the second outer plate and having an opening coincident with the attachment point of the middle plate;

    wherein rotation of an item attached to the torsion spring at the first attachment point rotationally displaces the middle plate relative to the first outer plate and the second outer plate and stores energy in the one or more first elastomeric elements and the one or more second elastomeric elements.
