Abstract: The present invention relates to a system for attaching a device to an object, comprising: an attachment device for attaching the device to an object, the attachment device having a trigger for triggering activation of the attachment device; a releasable coupling device for releasably coupling the attachment device to a deployment system. The releasable coupling device comprising: a housing; a trigger system, configured to trigger the attachment device trigger; and a retaining system, configured to releasably retain the attachment device. The releasable coupling device is configured such that: in a first configuration, the trigger system is in a disarmed state; in a second configuration, the trigger system is in an armed state, such that movement of the attachment device relative to the housing of the releasable coupling device activates the trigger of the attachment device; and in a third configuration, the retaining system releases the attachment device.
