American branch of organisation is proficient (5)

I believe the answer is:
adept
'proficient' is the definition.
(synonyms)
'american branch' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'branch' becomes 'dept' (abbreviation for department).
'a'+'dept'='ADEPT'
'of organisation is' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for adept that I've seen before include "Thoroughly proficient" , "Practised" , "Accomplished" , "capable" , "Dexterous" .)
