Furling eg rope I inserted into special coupling (7,2)

I believe the answer is:

coiling up

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

'furling eg rope' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'i inserted into special coupling' is the wordplay.
'inserted into' means one lot of letters goes inside another.
'special' indicates an anagram.
'coupling' is an anagram of 'coilngup'.
'i' put inside 'coilngup' is 'COILING UP'.

Can you help me to learn more?

I've seen this clue in The Guardian.
