Well you have to literally use the title for the module, so if you're assigned Theft of the Ur-Sword your module will need to be called Theft of the Ur-Sword. But in terms of how you interpret that for the content of your module is up to you.
So it could be a heist type thing, or maybe someone else has stolen the sword and the party needs to get it back? Or you could get weird with it, like someone stole the "idea" of a sword and now none exist lol
Does that answer your question?
