A spring assist module for a covering for an architectural opening, said spring assist module comprising a central member, a torsion spring including a first end and a second end, a first member coupled to said first end of said torsion spring, said first member being non-rotatably coupled to said central member, and a second member coupled to said second end of said torsion spring, said second member being coupled to a driven part of the covering for rotation with the driven part relative to said central member. The torsion spring is selected according to a protocol such that said torsion spring drives the driven part with a constant operating force.
