Abstract
A coil for transmitting torque comprises a wire having a longitudinal axis and first and second longitudinal edges extending along the longitudinal axis, wherein the first longitudinal edge is formed with a first pattern and the second longitudinal edge is formed with a second pattern complementary to the first pattern, the first and second patterns being configured to interlock with one another when the wire is wound into a helical shape.
