There is no Twisted API or special technique that you need to use.  Just 
create your objects with references to all the objects they need to 
manipulate.

For example, in main.py, instead of:

    reactor.listenUDP(self.port, transive_udp('...',2345, 0.05 ))

just do:

    reactor.listenUDP(self.port, transive_udp('...', 2345, 0.05, 
recive_data))

and then add an argument to transive_udp's constructor to refer to the 
data.

Similarly, you can keep a reference to transive_udp object in the main 
module.

I might be able to comment more except the attached example is full of 
errors and will not even import.
