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

'wrench' is the definition.
(I've seen this before)

'whiskey and recuperation' is the wordplay.
'whiskey' becomes 'w' (alpha bravo charlie delta ...).
'and' is a charade indicator (letters next to each other).
'recuperation' becomes 'rest' (I can't explain this - if you can you should give a lot more credence to this answer).

'necessitating' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.

Can you help me to learn more?
