Claim 8:
9. A system for torsion tracking, said system comprising:
a torsion device and a screw,
wherein said torsion device comprises a first distal plate, second proximal plate, and spring:
wherein said spring is disposed between said first distal plate and said second proximal plate such that said spring provides an opposing axial force between said first distal plate and said second proximal plate,
wherein said spring is configured to bias said first distal plate axially away from said second proximal plate,
wherein said first distal plate has a first bore extending through said first distal plate,
wherein said second proximal plate has a second bore extending through said second proximal plate;
wherein a shaft of said screw is positioned axially through said spring and through both of said first bore and said second bore,

a wireless tag comprising a first circuit portion and a second circuit portion,
wherein said first circuit portion is attached to said first distal plate and said second circuit portion is attached to said second proximal plate,
wherein said wireless tag forms a complete circuit when said torsion device is axially compressed due to torquing of said screw into an entity such that said first circuit portion and said second circuit portion abut one another,
wherein said wireless tag is configured to emit a signal when said complete circuit is formed; and

an interrogation device configured to detect said signal emitted by said wireless tag.
