Force in alternator questioned (6)

I believe the answer is:

torque

'force' is the definition.
(torque is a kind of force)

'in alternator questioned' is the wordplay.
'in' says the answer is hidden in the clue.
'TORQUE' is hidden in the letters of 'alternator questioned'.

(Other definitions for torque that I've seen before include "Force that produces rotation" , "Metal necklace; also a measure of force" , "Quoter (anag.)" , "Force tending to turn" , "Necklace of twisted metal" .)

I've seen this clue in The Telegraph.
