Make a straight reference curve for your spring, then make the curve line you want it to deform to
Select your spring, then use the deform flow command, select the straight reference curve first and then the curved one

This does deform the profile as you can see. If you want to make the spring profile constant then deform your helix first before you sweep the cross section to create the spring
