[EmsArnold]

Fixes #7

Instructions to reviewer on how to test:

1. Do dodal connect i15-1
2. Confirm hutch_shutter connects

Checks for reviewer

• Would the PR title make sense to a scientist on a set of release notes
• If a new device has been added does it follow the standards
• If changing the API for a pre-existing device, ensure that any beamlines using this device have updated their Bluesky plans accordingly
• Have the connection tests for the relevant beamline(s) been run via dodal connect ${BEAMLINE}

Thanks, just the one comment but happy to merge once you've addressed. I think we can do some work in combining all these shutters/interlocks down but hopefully that will fallout of #651

[DominicOram]

Should: Can we either check this before merge or make an issue to track that we need to check it?

[EmsArnold]

Ah whoops - I did check and updated the docstring, but forgot to remove the note! I'll do that
