I believe the answer is:

thumbscrew

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

'instrument of torture' is the definition.
(thumbscrew is a kind of instrument of torture)

'browses personnel' is the wordplay.
'browses' becomes 'thumbs' (I can't justify this - if you can you should give a lot more credence to this answer).
'personnel' becomes 'crew'.
'thumbs'+'crew'='THUMBSCREW'

'for' acts as a link.

Can you help me to learn more?

(Other definitions for thumbscrew that I've seen before include "That could be unpleasant!" , "It puts the squeeze on" , "excruciating instrument" , "agonised by it?" , "Instrument of torture (crushing the pollex)" .)
