Doctor Who finally given papers for automaton (5)
I believe the answer is:
droid
'for automaton' is the definition.
(both can mean a robot)
'doctor who finally given papers' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'finally' says to take the final letters.
'given' is a charade indicator (letters next to each other).
'papers' becomes 'ID' (identification papers).
The final letter of 'who' is 'o'.
'dr'+'o'+'id'='DROID'
(Other definitions for droid that I've seen before include "automaton" , "small robot" .)
