So what do you call a spiralled torsion spring like clock mainspring? A
spiralled spring? Is there a more common, clearer name?

"Clock spring" is the term I've seen most often.

I've always heard them called "helical springs."

An old text I have "Mechanical Design of Machines" (Siegel, Maleev,
Hartman) calls them "spiral springs". They are a special case of the
helical spring with the angle of the helix zero.
