Torque transmitter
First Claim
1. A torque transmitter including three coaxial helically wound springs, an inner spring, a center spring, and an outer spring, said springs having different inner and outer diameters and being positioned relative to each other such that said inner spring is surrounded by said center spring and said center spring is in turn surrounded by said outer spring, and said inner and said outer springs being wrapped in one direction and said center spring being wrapped in the opposite direction, said torque transmitter being characterized in that:
- the inner generally circumferential surface of said center spring forms an interference fit with the outer generally circumferential surface of said inner spring; and
,the outer generally circumferential surface of said center spring forms an interference fit with the inner generally circumferential surface of said outer spring.

Abstract
A torque transmitter includes three coaxial helically wound springs of different inner and outer diameters positioned relative to each other such that the inner and outer generally circumferential surface of the center spring form interference fits with, respectively, the outer generally circumferential surface of the inner spring and the inner generally circumferential surface of the outer spring. The inner and outer springs are wrapped in one direction and the center spring is wrapped in the opposite direction.
