Having no power, adjusted to the loss (9)

I believe the answer is:

toothless

I'm a little stuck... Click here to teach me more about this clue!

'having no power' is the definition.
I can't judge whether this definition defines the answer.

'adjusted to the loss' is the wordplay.
'adjusted' is an anagram indicator.
'to'+'the'+'loss'='totheloss'
'totheloss' is an anagram of 'TOOTHLESS'.

Can you help me to learn more?

(Other definitions for toothless that I've seen before include "Unable to chew; ineffective (sanction)" , "Deprived of power" , "Lacking in force" , "Lacking power" .)

I've seen this clue in The Sun.
