1. A deadbolt assembly for securing co-mounted doors together and activating at least one deadbolt, the assembly comprising:
a first-side assembly to be mounted within a bore of a first door of the co-mounted doors, the first-side assembly including a first coupling assembly to be mounted to an inside of the first door facing a second door of the co-mounted doors, the first coupling assembly including a first rotatable component and a first retention component;
a second-side assembly to be mounted within a bore of the second door including a second coupling assembly to be mounted to the second door facing the first coupling assembly so as to interact with one another upon bringing the first and second coupling assemblies toward and in contact with one another, the second coupling assembly including a second rotatable component and a second retention component;
at least one of the first-side assembly and the second-side assembly further including a deadbolt assembly that is operatively connected with one of the first and second rotatable components such that rotation of the first or second rotatable component can extend and retract a deadbolt,
wherein the first and second rotatable components are operatively connectable with one another and the first and second retention components create an interference in an axial direction of the first and second rotatable components upon bringing the first and second coupling assemblies in contact with one another along with rotation of at least one of the first and second rotatable components so as to restrict movement of the first and second coupling assemblies away from one another while the interference is created.
