[UPDATE: should be the right solution to prevent the module being include several times in the same class]

I believe you can use ActiveSupport::Concern to prevent the module being include several times which result by callback called several time. See the example below :

module VotePatch
  extend ActiveSupport::Concern

  included do
    after_create :create_activity_stream_event
    has_one :activity_stream_event
  end

  module InstanceMethods
    def create_activity_stream_event
      #your code here
    end  
  end

end

Vote.send(:include, VotePatch)
