Bluetooth on iOS is a mess. If you are paired but not connected to a device, all you can do is forget it.
If you are paired and connected, you can:
* Change the name of the device as it appears on your phone
* If it's an audio device change its function (for example "car stereo", so iPhone will not automatically decrease volume if you put the volume to max which it will do for "headphones", as you probably control volume from the car stereo itself)
