1. A covering for an architectural opening, said covering comprising:
a rotator tube; and
a power assist module configured to be installed within said rotator tube, said power assist module comprising:
a spring having a first end and a second end;
a tube adapter member positioned adjacent to said first end of said spring, said tube adapter member coupling said first end of said spring and said rotator tube such that said tube adapter member rotates with both said first end of said spring and said rotator tube when said power assist module is rotationally driving said rotator tube; and
a rotatable component positioned adjacent to said tube adapter member, said rotatable component configured to be axially decoupled from said tube adapter member to allow said rotatable component to be rotated relative to said tube adapter member;

wherein rotation of said rotatable component relative to said tube adapter results in said spring being wound to adjust a spring force of said spring.
