Adjust shattering moves (10)
I believe the answer is:
straighten
'adjust' is the definition.
(I've seen this before)
'shattering moves' is the wordplay.
'moves' indicates anagramming the letters.
'shattering' anagrammed gives 'STRAIGHTEN'.
(Other definitions for straighten that I've seen before include "put in alignment?" , "Remove bends from (something)" , "Get in line" , "Align correctly" , "put back in order" .)
