Abstract
A tubing hanger assembly includes a body, a lockdown feature which is located on the body, a load nut which is threadedly connected to the body and which includes a downward facing load shoulder, and a torsion spring member which includes a first end that is connected to the tubing hanger and a second end that is connected to the load nut. In operation, the torsion spring member rotates the load nut to thereby move the load nut axially relative to the body. In this manner, the axial distance between the load shoulder and the lockdown feature is adjustable.
